This adventure is designed so that it cannot be adequately completed by a skilled partly at level. In fact, I don't see how it could be completed unless the players are literally psychic and guess their way into the correct solution in time. It looks a lot like you're meant to believe your party can have an impact on the metaplot, but you're actually just meant to lose, and that's a terrible game experience. 0/5 stars, arguably worse than Lions of Katapesh.
